Abstract
This project focuses on the ecological and cultural restoration of Powers Creek, a tributary of the Baduwa’t watershed at Blue Lake Rancheria, California. Riparian ecosystems play a critical role in biodiversity, water quality, and climate resilience, particularly for species like salmonids reliant on cold-water refugia. The restoration efforts, guided by Indigenous knowledge, addressed the removal of non-native competitive species such as Scotch broom (Cytisus scoparius) and French broom (Genista monspessulana) – which are shown to increase wildfire severity and challenge native plant communities – in addition to freeing established plantings of vegetative competition. Through collaborative planning with the Rancheria, this study employed mechanical removal methods and geospatial mapping to assess site conditions and plant survivability. Results indicated higher mortality rates for plantings situated in rockier substrates and highlighted the resilience of certain culturally significant species over others. Recommendations include continuous prolific species management, future bank stabilization efforts for the growing cut bank on site, the inclusion of cultural burning practices to suppress seed banks, and targeted replanting efforts to aid the shift in dominance back to native species. This integrated approach centers Indigenous knowledge and fosters long-term ecological and cultural sustainability through Indigenous stewardship frameworks.
